Getting around MEX
Benito Juárez is built as two terminals that share nothing but a runway system — Terminal 1 and Terminal 2 sit on opposite sides of the airfield, roughly nine-tenths of a mile (1.4 km) apart, as measured on the airport’s own footprint, with no shared curb or walkway between them. The Aerotrén that links them is not a public shuttle: the airport reserves it for travellers already in connection, e-ticket or boarding pass in hand, plus flight crews, running 05:00 to 01:00 daily. Everyone else has two paid ways across the field: TETSA, a private operator that has run buses between Gate 7 (T1) and Gate 4 (T2) since before 2021, cash on board; or Mexico City’s own Metrobús, which boards at Gate 7 (T1) and Gate 2 (T2) and added a dedicated inter-terminal shuttle in August 2026 alongside its older route into the historic centre. The Navy has run the airport since October 2023, when a presidential decree folded it into the Secretaría de Marina, and federal regulators cap how busy it can get in the air: the hourly landing-and-takeoff ceiling was raised from 44 to 46 in May 2026 as new rapid-exit taxiways came online, after years of tighter limits imposed for runway safety. None of that slowed passenger growth — 44.6 million people passed through in 2025 — and, as of January 2026, the two terminals split traffic almost evenly (48/52), per the airport’s own monthly count.
